Even if you stayed overnight, on their doorstep, and they still didn't show up?

Which is probably what the scouts did. Even if you searched the premises to see where they could be? Even if the neighbours didn't know where they were? Even if their were indications that no-one had been inside for days/weeks/months? Even if you couldn't contact them? Even if after you left, they didn't get in contact?

I think you're looking at this far too much from a real life situation. In Middle-earth, Radagast was missing. And that's that.
